Brain-Computer Interface

A technology that enables direct communication between the brain and an external device by detecting and interpreting neural signals. BCIs can use invasive methods (implanted electrodes) or non-invasive approaches (EEG headsets). In accessibility contexts, BCIs allow people with severe motor disabilities to control computers, communication devices, or prosthetics using thought alone. While still emerging, BCIs represent a potential solution for individuals who cannot use other input methods including eye tracking or switch access.
